Material & characteristics
An open structure for rapid drainage
The coarse particles leave generous spaces between the granules. Water can move away freely while air circulates through the root zone.
- Stable granular structure: The granules retain their shape and do not break down inside the pot.
- Large air spaces: The 8–16 mm particles encourage rapid water flow and generous airflow.
- pH-neutral: It is not intended to alter the chemistry of the nutrient solution.
- No nutrients: Nutrition is supplied separately and adjusted to the plant and growing system.
Rapid drainage
The larger granules allow excess water to move away instead of pooling around the roots.
More air around roots
Open spaces support air exchange throughout the root zone.
Support for strong root systems
The stable mineral structure suits larger plants and roots that need room to develop.
Preparation & use
Prepare it correctly in four steps
Transport dust is normal with a granular mineral product. A quick rinse or wetting helps remove it before planting.
- Hydroculture
- Semi-hydro
- Larger plants
- Drainage layer
- Potting-mix amendment
- Top dressing
Use clean water to bind and remove fine transport dust.
Use it alone in a hydroculture system or as a mineral drainage component.
Arrange the roots and add the granules gradually so the air spaces remain open.
Follow the plant's needs, the water-level indicator and the fertiliser instructions for your system.
Expanded clay is not a fertiliser
The material contains no built-in nutrients. In hydroculture or semi-hydro, use a suitable fertiliser and follow that product's dosage instructions rather than applying an improvised ratio.
Pack size
Blusana · 25 L
The 25 L pack is practical for larger containers, several repotting jobs or more extensive drainage applications.
Product condition
Ready after rinsing
Rinsing does not change the material; it simply removes fine dust that can form during transport.
Storage
Keep the pack closed in a clean, dry place. After reuse, clean the granules and allow them to dry completely.

Frequently asked questions
Quick answers about particle size, preparation and correct use.
01What is Blusana Plant Clay?
It is pure expanded clay made from natural clay fired at high temperature. This is a stable, porous mineral material with no organic ingredients or built-in fertiliser.
02When should I choose the 8–16 mm size?
Choose the coarse size when you want larger air spaces, rapid drainage and room for a stronger root system.
03Should I rinse it before use?
A quick rinse or wetting with clean water is recommended to remove fine dust that can be produced during transport.
04Does it contain fertiliser?
No. For hydroculture, add a suitable fertiliser separately and follow the dosage and schedule for that specific product.
05Can it be reused?
Yes, provided the granules remain in good condition. Remove roots and residues, clean them carefully and allow them to dry before using them again.
06Are differences in colour or texture normal?
Yes. As the raw material is natural clay, minor differences in colour, surface and shape between batches are normal.
